| The Aim of this study has been to evaluate in two two-year field trials the pre-crop effect of different grain legumes (e.g. soy bean, peas or lupines) in the same environment and to detect possible effects of grain legumes on the N-supply, the yield potential and the yield structure of the subsequent crop winter wheat. According to different pre-crop yields, a higher but different nitrogen supply for subsequent winter wheat was observed in all N2-fixing pre-crop treatments. In contrast to non-fixings control higher NO3-N contents in soil and higher yields in subsequent winter wheat (up to 24 dt*ha- 1 surplus) were observed. |

| An improved Decisions Support System (DSS) for the control of Phytopththora infestans in organic potatoes was developed in the frame of the CoFree Project. This work included as primary steps the development of an ontogenetic model (Simonto) based on the BBCH scale of potatoes, and its validation. Additionally, the soil mineral nitrogen dynamics in organic potatoes and nitrogen contents of tuber and leaves were modelled and integrated in the existing DSS Öko-SIMPHYT (www.isip.de). The DSS comprises a correction tool at BBCH 60 for the user to improve the quality of the prediction of potato growth and a termination of copper spraying when potential yield of 90 % is reached. This development was based on intensive data mining in existing data sets from... |
